A burned out brake light bulb can do this, too.

Burned out brake light bulb and also I had a 3rd brake light for a fiberglass cap that was spliced into the brake light wiring harness...every time it got wet and I tapped the brakes it would shift out of O/D...I respliced it and shrink wrapped all connections and the problem went away.

powerstroke auto tranny problem #2

hi guys i'm new to this so i hope you see this message thanks alot ,i will check the bulbs and see if there are any splices in the harness. before i saw your posts i seem to have developed another problem. my tranny seems to be hunting for a gear and goes into neutral and and back to another gear. at home and tried to restart it, it wouldn't even turn over so i jumped the starter relay and it fired up .i put my scanner on and i got a code saying not in park or neutral. i am assuming my manual lever position sensor is faulty but could anyone tell me if they think my two problems could be caused by the same thing. i am going to put on a spare mlps. that i have but am unsure of how to get it lined up so that my shifting problem doesn't get worse and i screw up my tranny. any advice would be greatly appreciated i will wait to see if i get any posts before i attempt this

thanks for your time
